In the form may and is assumed to be after aconsiderable shown, where the bucket elevator is symmetrically 45interval, there will always be one or more corn=- located with respectto the receiving member and pletely filled cans to be emptied andtherefore no discharges the ashes into it more or less cen= necess y oroccasion to raise dust and scatter trally, the desired result isaccomplished by plac ashes in the neighborhood of the stolrer by coiningthe mouth of outlet 6 so as to be intersected v pletely filling one ormore of the cans from the by the axis of member 3, and the outlet ofisetto others. In other words, if, in the. interval be with respect $01??-tween ash disposals, a quantity of ashes sumcient Withthis constructionit follows that all of the to fill only one can has been discharged fromthe ashes first passing down through member 3 will 'stoker, all of suchashes will bein one can and not discharge by way of outlet 5, into itscan t and s5 partially filling two or more oil them. that t willcontinue until such can and its out= lid r of rest of the material.

distance above the bottoms of the cans.

let are filled substantially to the height indicated by the line 59(Fig. 2), the accumulation being more or less conical in accordance withthe angle Thereafter, however, as the height of the cone tends toincrease, the ashes delivered strike this accumulation and overflow asit were, through outlet 6 and into its can 9, which in turn is filled.Although each outlet is thus filled, as well as its can, I have foundthe ashes are so lightly packed that if each can is struck or shakenprior to its removal to be emptied, the ashes settle down and those inthe adjacent outlet are easily accommodated in the respective cansprovided the diameters of the outlets or spouts tl and 65-41 aresufficiently smaller than the diameters oi the cans and the dischargeends of these outlets or spouts are located at a suitable It ispreferred, but not altogether essential, that the downward slope of thebottom of each oi the out-1 lets be somewhat greater than the angle ofrest or the material; with ashes, this angle is about 45, which is theangle at which I usually slope the outlets; strictly speaking, it isonly necessary that the outlets or conduits 5 and t provide passagewaysleading downwardly at an angle to the horizontal greater than the angleor rest oi the ashes in the passageway.

Where it is desired to use more cans, a three wayreceiving member, such.as illustrated in 3 may be employed. The principle oi operation is thesame. After the central outlet it has filled (following the filling orits adjacent can) the ashes flow through outlet if), as before, andthen, when the level rises to the line it, they pass through outlet M,which is at a higher level, to the can supplied thereby. in fact thenumber oi outlets and cans is dictated solely by the requirements of theparticular installation. For large installations, seven is a convenientnumber of cans to use since, as indicated in Fig. l, they are capable ofarrangement within a comparatively small compass, the six cans it beinggrouped closely around the central can it but usually slightly spaced onthe stolser side to accommodate the elevator casing ii. A receivingmember for supplying and successively filling such cans is illustratedin Figs. a and 5, there being a central outlet it and six lateraloutlets variously placed around the wall of the member. To avoidincreasing the height of the receiving member unduly to allow foroutlets at six difierent levels, I prefer to arrange the lateral outletsin pairs, the ones marked it being at one level, 2i) at another and iiat still a third level, as indicated in Fig. 5; as between the twomembers of each pair, these may be placed in the manner illustrated inFig. 2, or otherwise. As above described, the cans are filledsuccessively but, after the first or central one, in pairs. In aninstallation of this capabity there may thus he, say, five completelyfilled cans to be emptied instead of that quantity of ashes distributedamong all seven without filling any of them. In each case, as abovementioned with respect to the two-can assembly, the ashes filling up theoutlets and the adjacent portion of the body member (as each outlet isfilled and the next comes into action) are readily shaken down into therespective cans.
